Keto is just another name for very low carb diets--Atkins is one of them. It can sure get confusing with all the names.

The first couple of weeks can be really tough while you're trying to break the carb habit and you're surrounded by people eating the stuff and encouraging you to do the same. Make sure you have lots of good food in the house and get rid of all the carbs. Throw it out, give it away, whatever you have to do.

Then make sure you're eating plenty of good protein and don't shy away from fat. If you're hungry, eat something (not carbs). If you have cravings for carby food, eat something with protein and fat.

Your first goal is to just make it through the first couple of weeks. Some people find using replacement sweeteners like Splenda or stevia useful during this time and other people like the cold turkey approach. Do whatever you need to do to just stay on plan. After that it becomes easier to stick to and if you need to make tweaks, you can. For now keep it simple: Don't eat carbs and don't be hungry.
